WATER HEATER.

Specification of Letters Patent. Patented Jan. 17, 1922.

Application filed June 26, 1918. Serial No. 242,043.

To all whom it may concern:

Be it known that I, FREDERICK W. Sorronrrnn, a citizen of the UnitedStates, residing at Oak Park, in the county of Cook and State ofIllinois, have invented new and useful Improvements in Water Heaters,-of which the following is a specification.

This invention relates to hot water heaters employing a gas burner forthe heating mcdium. The heater is designed more partlcularly forhot-water heating plants, a though it may also be used as a steamgenerator for steam-heating plants.

The invention has for its object to provide a very simple and efficientheater of the kind stated which can be readily installed and which iscapable of being connected to any ordinary coal-burning hot water orsteam heating system already installed.

The object stated is attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed, and inorder that the same may be better understood, reference is had to theaccompanying drawings, forming a part of this specification.

In the drawings,

Figure 1 is a vertical section of the heater, and Fig. 2 is a horizontalsection on the line 2,2'of Fig. 1.

Referring specifically to the drawings 10 denotes a suitable standsupporting a sheet metal or other casing 11. In the upper part of thiscasing is mounted a water container 12 of cylindrical form, and belowthe same is located a series of water heating coils13 which arevertically positioned. These coils are heated by a gas. burner, a burnerunit l being positioned beneath each coil. The coils and burners arealso enclosed in the casing 10. The coils are fitted at their bottom bymeans of pipes 14: to a supply connection. At the top, the coils areconnected to the container 12, each coil being connected by a pipe 15 toa coupling 16 from which latter a pipe extends and is connected to thebottom of the container. From the topof the container extend pipes 17which connect to the mains that supply the radiators. It

may be here stated that the heater is inv tended for hot water, steam orvapor heating plants. For a hot water heating plant the container willbe kept full, whereas for a steam heating plant it will be kept partlyfilled to obtain a steam collecting space.

Between the top ofthe coils 13 and the bottom of the water container 12is located a heat concentrating hood 18 which is dimensioned to extendcompletely across the insideyof the casing 10, and has a flared centraloutlet 19 at the top to direct the heat against the bottom of thecontainer 12. This hood, holds the heat from the burners 1 around thecoils 13 so that the water therein is quickly heated.

' To the top of the casing is connected a draft flue 20 provided with ahood 21 to prevent sudden up or down drafts from extinguishing theburners 14. The flue has two vertically spaced sets of openings 22 and23, respectively, and the hood; is mounted on the outside of the flueoverthese open= into the hood 21, and then returns bythe way of the topopenings 22 into the flue. The cone is principallyintended to serve as abattle, however, to protect the burners 14 from down drafts. In theevent-of a strong down draft through the flue, the cone de-' fleets thesame sidewise through the top openings into the hood, thus preventingthe burners 14: from being extinguished.

Beneath the inlet end of the flue 20 is a bafile plate 30 which permitsthe fumes to escape, but prevents the heat accumulating about thecontainer 12 from rising directly into the flue.

I claim: I r v In a water heater, a casing, a water con tainer locatedin the casing, a series of ver tically positioned heating coils'beneaththe container and connected thereto, heating burners beneath the coils,and a heat retaining hood in the casing closing up the same between thebottom of the container and the top of the coils, said hood having a topopening located beneath the bottom of the container to direct the heatthereagainst.

In testimony whereof I affix my signature.

FREDERICK" W. SCHOETTLE.
